Largest Known Astroid may be a Mini Planet

I was going through a website called www.sciencedaily.com trying to find something that interested me, when I accidently stumbled upon this article. Scientists believe that Ceres, the largest known astroid, may contain a layer of ice consisting of pure water. This astroid contains many similar characteristics to Earth and other rocky, terrestrial planets. It is quite possible that it may have more water then all the fresh water on earth. Although it is extremely smaller then all of our planets, it is interesting how it shares similar features with some of them.
